Parameters for good welding of copper to nickel
Quality in welding copper leads to nickel bus wires is obtained by the mass of nickel exceeding that of copper. Welding range 2ncreases proportionately with the increase in the nickel-to-copper mass ratio up to 4-to-1.

Quality-weld parameters for microwelding techniques and equipment
Limited-amplitude, controlled-decay process improves the reliability of microwelding. The system consists in building a capacitor-discharge welder for control of the shape of the weld pulse. Standard welders may be modified.

Spherical ion source
Radial focusing of electrons in ion source produces greater ion densities, resulting in higher resolution and focus capability for a given source volume. Electron beam is focused near exit aperture by spherical fields. High density ions allow focusing ion beam to high density at echo, allowing high current through small aperture.
